According to the Washington Post, noted orthopedic surgeon Dr. James Andrews
will determine how much damage has been done to the ACL when they perform the
surgery.

Griffin was examined Tuesday outside Pensacola, Fla., by Andrews. The trip was
needed after an initial MRI exam proved to be inconclusive.

Coach Mike Shanahan said on Monday that Griffin was going for more exams
because there was an issue distinguishing between old and new injuries in a
knee that's had previous ACL and LCL injuries.

Griffin left Sunday's 24-14 playoff loss to the Seattle Seahawks in the fourth
quarter after falling to the field in agony. He remained on the ground for
several minutes before getting up on his own power and walking off the field.
He did not return.

Griffin originally injured his right knee in a Week 15 win over the Baltimore
Ravens and sat out in Week 16. Griffin returned to action and guided the
Redskins to a 28-18 win over the Dallas Cowboys and the NFC East crown in the
regular-season finale.
